死锁疑问

如下代码, 可以直接跑 ``` func Count(ch chan int, i int) { fmt.Println("counting ", i) ch <- 1 } func main() { chs := make([]chan int, 10) for i, _:= range chs { chs[i] = make(chan int) go Count(chs[i], i) } for _, ch := range chs { <-ch } } 但是换成下面这种就不行了,报死锁的错误 func main() { chs := make([]chan int, 10) for i, ch:= range chs { ch = make(chan int) go Count(ch, i) } for _, ch := range chs { <-ch } } ``` go 版本是1.13.4 小白一个,不是很明白, 盼望大佬解惑.....
